FRIENDS OF YOURS 

'VERY DAY we hear someone say "Why do we have so 

many more insect pests now than we used to have? 

I can't raise a thing — fruit, flower or vegetable — 

without a pitched battle with insects." 

We have been killing insect-eating birds by the thousand 

for fun and for food and by the million for their feathers. 
Our forests are being cut down and the 
few trees that remain in our cities and 
towns are being hacked and trimmed by 
the telephone and trolley companies until 
l^ut a few stumps remain, and but few 
artificial nesting or retreating places are 
replacing the natural ones destroyed. 

While our helpful birds are being 
driven away and killed we offer protected 
nesting places in the cornices and eaves 
of public buildings and an abundant food 
supply from street droppings to the 
foreign, not-fit-to-be-naturalized, piratical 
English sparrow, who destroys the young 
of the insect-eating birds and lives on 
seed and grain himself. Thus Man has up- 
set one of the most important balances 
established by na- 
ture to control the 
'nsect growth and is 
paying for his folly 
by the increased 
number of insect 

pests. In our efforts to restore this bal- 
ance every natural insect enemy should 

be encouraged and instead of getting 

after the thousands of worms we should 

go after the butterfly before she lays 

her eggs. Part of the millions spent for 

poison and spraying should be used to 

exterminate the egg-laying butterfly and 

moths. Here again the bird helps, as 

moths are one of their special "tid-bits." 
Do not spread insects, or allow an 

opportunity to pass for destroying 

them. Every one can help a little. 

The mother who tells her little 

son to "let the little birdie go and not 

harm it," when he traps a butterfly 

under his hat, helps to keep up the high cost of destroying

insects. That caterpillar you brushed from your coat at 
Cieanville and neglected to crush, may 
have boarded you fifty miles back in 
Bugtown, and it may cost the taxpayers 
of Cieanville a million dollars to control 
or exterminate his progeny. 

Protect the birds. They are busy 
long before you are awake and their keen 
eyes can detect insects rods away that 
are invisible to the human eye even when 
close at hand. Invite them with pro- 
tected nests, bathing places, and a little 
food hung at convenient places, and as 
soon as they make their home near you 
your insect troubles will decrease and you 
will have interesting neighbors who will 
furnish you with the sweetest music* 

Use as little poison as possible for 
killing insects, resort to mechanical 
means when practical. Starve the Eng- 
lish sparrows, kill them and at every op- 

— portunity destroy their nests. Turn the 

cat loose on them and equip "the boy" wi th an air gun. Give 
no quarter to these pirates, the great 
bird enemy of our helpful birds. 

There are many other natural insect 
enemies. There is no more energetic, 
always-on-the-job insect eater than the 
common homely, ordinary toad, tie is 
a most persistent exterminator of ants, 
caterpillars, plant lice, spiders, snails, 
grasshoppers, angle worms, tomato 
worms, flea beetles, in fact almost every 
insect is acceptable to him. Animal 
matter constitutes ninety per cent, of 
his food and the number of insects re- 
quired to satisfy his appetite is enor- 
mous. In France many firms do a thriv- 
ing business loaning and selling toads 
ito farmers and gardeners. It has been 
iestimated. that based on the cost of kill- 
ing the number of insects with poison 
ithat a toad would destroy, they are 
rworth over $5.00 each.

Broadway, New York City, furnish pamphlets on "how to 
attract birds."

Lady Bug Beetle 



Always help a toad along, encourage him, by leaving him 
alone, to remain on your premises. Make shallow holes in 
the ground and cover them with flat stones or boards. They 
will use them daytimes for shelter. Farmers and gardeners 
wherever possible should propagate toads. They breed in 
swampy places the same as frogs and 
little toad, tadpole, requires little or 
no attention. Toads generally remain 
near the locality where they are raised 
providing the food supply is plentiful. 
All insects are not injurious. One 
of the best known beneficial insects is 
the lady bird, sometimes called lady- 
clock, lady cow. lady fly, lady bug, but 
known best as "lady beetle." There are 
some ten species of this well known 
friendly insect, which is very destruc- 
tive both as beetles and larvae, to many 
forms of insect life, especially to aphis. 
They are hemispherical in form, with a 
smooth, polished surface, and are often 
colored red, brown, or black with small 
spots of brighter colors. About the 
worst sin committed by toads is that 
they occasionally (by mistake no doubt?) kill one of these 
helpful insects, but this trangression is not frequent. These 
Lady Beetles as well as their young or larvae are often mis- 
taken for injurious forms and are unfortunately killed. The 
Lady Beetle young vary in length all the way up to about a 
half inch, are bluish or blackish in color, often with orange 
spots on the back, and resemble very much a miniature alli- 
gator in general appearance. They crawl about freely and 
do wonderful service in destroying large numbers of plant 
lice, scale insects, etc. 

Always encourage and make existence eas5^ for the natural 
insect enemies, birds, toads, helpful insects and parasites.

YOUR INSECT ENEMIES 

CHE GREAT difference between insects, their habits, 
food and methods of attack, makes it imperative that 
you study insect troubles before you try to remedy 
them. There is no such thing as success for the "hit 
er miss" fellow in fighting insect pests. Tou must apply the 
right material at the right time, thoroughly, and anyone not 
willing to inform himself sufficiently to do this is just as 
sure of success as a boy v/ho set a mouse trap for a crocodile.

YOUR INSECT SNEMTBS — Continued 

Don't scrimp on quality or quantity when buying insect 
killers and fungous remedies. The best is none too good. 
Scrimping <o save not over twenty cents on an acre of pota- 
toes once made a difference between a full crop and a total 
failure. Buy reliable goods made by reliable makers and 
apply them liberally according to directions. It takes just 
as much time to apply a poor article as it does a good one. 
Use a poor one and you stand a chance of losing the crop you 
wish to save, the time it takes to apply and the cost of the 
goods. 

Spraying for fungi and insects is not an expense. It is 
an insurance that pays "big." Take it into consideration 
when planting as part of the necessary investment. It is just 
as important as cultivating or fertilizing. If you cannot 
afford time or money to protect your crops after they are 
planted, don't plant them. 

With the down-to-date mixtures the caring for crops 
has been greatly simplified, for instance, Sterlingrworth Ar-Bo 
(see page 48) kills most fungi and leaf eating insects with 
one spraying. It is the great apple and potato spray. Tears 
ago three, perhaps four, sprayings would be required to do 
what Sterling-worth Ar-Bo does with one. 



FUNDAMENTALS OF INSECT 
CONTROL 

a PON THE way in which an insect obtains its food 
depends usually the control measure to be used against 
it. From a practical standpoint, insects feed in one of 
two ways, either by (1) biting off and swallowing 
particles of solid food, as in the case of caterpillars, beetles, 
etc., or (2) by sucking the juices of plant or animal, as in the 
case of plant-lice, scale insects, etc. 

Accordingly there are three chief ways of attacking insect 
pests. 

(1). By placing a poison on the food so that it is swal- 
lowed with the food. Such poisons act in the stomach and 
are called stomach poisons. Sterlingwortli arsenate of lead 
is a common stomach poison. These are used against leaf- 
eating and other insects which bite off and swallow food. 
such as caterpillars, leaf, beetles, etc. 

(2). By hitting insects with materials which kill by con- 
tact with their bodies. Such materials are called contact 

Page four sTERUNe chemical co.. Cambridge, mass.

FUNDAMENTAZ.S OF INSECT CONTBOIi — Continued 

insecticides. Soap solutions, nicotine sprays, kerosene emul- 
sion are examples of contact insecticides. These are used 
ag-ainst insects which pierce beneath the surface of a plant 
or animal and suck the juices, such as plant-lice, scale insects, 
etc. A stomach poison would be useless against sucking in- 
sects since they pierce beneath the surface upon which the 
poison is spread befor'e feeding- is begun. Success with a con- 
tact spray depends almost entirely upon thoroughness. EACH 
INSECT MUST BE HIT BY THE SPRAY TO BE KILLED. 
A contact insecticide .should be strong- enough to destroy the 
insect against which it is being used and yet weak enough 
so that it will not injure the plants which are subjected to it. 
(3). By using poisonous gases. These kill all kinds of 
insects but they can be used only under certain circumstances. 
The chief gases which are used ag-ainst insects are carbon 
l)isulphide, hydrocyanic acid gas and sulphur fumes. 



CONTROL OF LEAF AND FRUIT- 
EATING INSECTS, BORERS, ETC. 

"'^^^^HESE insects are usually controlled by spraying a 
m C\ poison over tlie food which the insect is eating or by 
^ J mixing a poison witli the food. Materials, which give 
^^^^ off poisonous vapors, are often used against borers in 
trees, etc. Practices known by the general term "Farm 
Practice," such as trapping insects, late fall ploughing, de- 
sti-uction of insects by cutting them out of infested plants, 
etc., are often employed without the aid of insecticides. 

AFFI.X: MAGGOT OB BAII«BOAD WORM. The apple 
maggot is the young of a small barred-winged fly less 
than a quarter of an inch long. The flies puncture the 
skin of apples, especially summer and autumn varieties, such 
as the Red Astrachan, Bough and Wealthy, and lay their eggs 
in the pulp beneath. The eggs are usually laid during July. 
The maggots "railroad" through the pulp ruining fruit which, 
to outside appearances, is perfectly sound. The work of the 
apple maggot can be distinguished from that of the codling 
moth, since the larvae of the latter feed almost entirely about 
the core. 

CONTBOIi. Spray foliage of susceptible varieties two or 
three times at intervals of ten days, beginning July 1, with 
the following:

SOBERS, ETC. — Continued ^P 

Cheap molasses or syrup 13 pounds 

Sterlingworth Arsenate of lead 2 1-2 pounds 

Water, 50 gals. 

A coarse spray is preferable. A pint of this mixture 
should be enough for a medium sized tree. This destroys the 
adult flies before they lay their eggs. It is not attractive to 
bees. 

ASPARAGUS BEETI^ES. There are two 
common asparagus beetles. One is bluish- 
black and has yellow marks on the back. 
The other species is of a light brown color 
with twelve black spots on the back. The 
eggs are black and are laid on the asparagus 
stems. These eggs hatch in from six to ten 
days and the greenish grubs feed until ma- 
turity, when they drop to the ground, change 
to pupae and the adults emerge soon after. 
There are several broods each year. 

REMEDY. Let chickens run through 
the rows. The beetles prefer to lay their 
eggs on the tallest stalks. Keep some of 
these stalks for traps and either spray 
them heavily with Sterlingfworth Arsenate 
of ILead or cut and burn them from time to 
time. Dust the plants in the morning while 
the dew is still on, with air-slaked lime. 
This will kill many of the young grubs. As Asparagus 
soon as the cutting season is over, spray the Beetle 

plants heavily with Sterling-worth Arsenate 
of Iiead and repeat a month later if the beetles are still nu- 
merous.

middle of June they have their growth and 
are from one to one and one-half inches 
long, brownish in color, quite hairy, with a 
line of white spots on each side of back. 
Near the rear end of the back there are two 
large, brilliant orange spots. The hairs on 
the sides of the body are barbed. These 
the caterpillar sheds at maturity, and per- 
sons upon whom they fall suffer from a 
serious unpleasant itch. When matured 
they spin a cocoon around themselves and 
emerge as a moth in about two weeks. The 
female is about one and one-half inches 
from tip to tip of wings and is clear white 
except that she has a large tuft of brown 
hairs on the extreme rear end of her body. 
These moths are great night fliers and cover 
great distances. This makes it impossible 
to limit their zone of operation. They are 
greatly attracted by bright lights, which 
would seem to suggest a method of exter- 
mination worth considering. Some non- 
poisonous, mechanical method of killing the 
moths must be discovered or it will cost 
morft <ban the Civil War to hold this insect 
in check. 

Bemedy: Clip off the nests during the 
winter and burn. If you neglect to do this, 
spray with Sterling-worth Arsenate of Iiead 
(See page 49). They attack all fruit trees 
and a large number of ornamental shrubs 
and shade trees. 

BUD MOTH OB BUD WOBM. The 
worms or larva winter in a half- 
grown state in a silk cocoon patched 
with bits of leaves and bark attached to the 
tree twigs. They emerge at apple budding 
time as worms about three-sixteenths of an 
inch long. They feed at night on the buds 
and tender foliage. In six to eight weeks 
they get their growth, form a cocoon by 
cementing leaves and tieing them together 
with silken threads. A change to moth 
occurs in ten to twenty days. The moth 
lays eggs on the under side of leaves which 
hatch in about ten days. This new crop of 
larvae or worms spin a web of silk for their 
protection while they feed upon the tender

leaves until frost time, then they hibernate until spring. 
These insects cut down fruit crops by destroying- the buds. 

Remedy: If you spray for codling moth the same sprav 
will usually protect agrainst this pest. In old orchards or 
where bud worm injury has been severe in the past, spray 
with Sterlingrwortli Ar-Bo (page 48) as soon as the buds un- 
fold in the spring-, and force the spray well into the new 
growth. 

CABBAGE WORM. The mother butterfly is clear white 
— one and three-fourths inches across from tip to tip of 
wings. Tips of wings are dark. Each front wing has two 
black spots — each back wing has one black spot. In New Eng-

Cabbage Worm in the center of the head. 

They mature in two or three 
weeks, reaching a length of 
about one inch. They crawl to some secluded place and 
change to the chrysalis stage, from which the parent butter- 
flies appear about two weeks later. There are several broods 
each year, the winter being spent in the chrysalis stage. 

Control: Duiing the first two months of growth, cabbage 
l)iants (it is claimed by many) can be sprayed with Sterling'- 
worth Arsenate of lead without danger of poisoning from 
eating the plants later. Chemical tests seem to have proved 
this. A whale oil soap solution added to the Aisenate of lead 
aids in sticking- it to the plants. After the plants are well 
headed, if further treatment is necessary, use Sterlingrworth 
Hellebore (page 54) or Sterling-worth He-Bo, see page 54. 

CABBAGE IiOOFER. The history of this insect is similar 
to that of the Cabbage Worm. Tlie larvae which does 
the eating is a green worm about one and one-fourth 
inches long, has no legs in center of body and crawls with a 
looping motion. Cabbage Loopers attack the same vegetation 
as the Cabbage Worm. Remedy the same.

about seven-eighths of an inch long and are as big

put tanglefoot directly upon bark 
of young fruit trees. Injury may

Most of the eggs are placed on the 
leaves. These hatch in the course 
of several days and the young worms 
usually feed a little on the tender 
leaves before they make their way to 
the young fruit and bore into it through 
the blossom end. Practically all of the 
feeding is done about the core. About 
mid-summer these larvae become full 
grown, bore out to the surface and seek 
a place to form their cocoons. There is 
sometimes a partial second brood in 
Massachusetts, the moths of which ap- 
pear late in July or early August. 

Control: Spray apple and pear foli- 
age and fruit just after the blossoms fall 
with SterUng-wortli Arsenate of lead, 
page 49 or Sterlingrworth Ar-Bo, (page 
48). Don't delay this application. It 
will be worthless if delayed. Force the 
spray into the blossom ends. At this 
time the calyx sepals are open and will 
hold some of the poison ready for the 
v/orms when they begin to bore into the 
fruit. The calyx sepals close a couple 
of weeks after the blossoms fall and it 
will then be too late to place the poison 
where it will be effective. Make a sec- 
ond application ten days after the first 
for best results, and spray about the 
first of August for the second brood. 
Sterlingrworth Ar-Bo (page 48) will not 
only control the codling moth but certain 
fungous diseases as well. It is a double 
spray, combining two operations in one. 

CURCU]tIO. This insect attacks ap- 
ple, pear, pluin, peach, cherry and 
all pome and stone fruits. The 
adult beetle is one-fourth of an inch long, 
dark broAvn in color with gray mottles; 
has six legs, a very chunky body about 
half as wide as the beetle is long. The 
head and snout are shaped like the letter 
V. With this V-shaped bill a hole is 
punctured in the fruit and the pulp ex- 
tracted as far as the bill will reach and

CONTBOIk OF JmEAT AND FBUIT-EATING, INSECTS, 
BOBEBS, ETC. — Continued 

an egg deposited in the hole which is then plugged with a 

sticliy excrement. The eggs hatch in three to six days and 

the resulting grub commences to burrow into the fruit. 

This is its sole vocation for two or three weeks, when the 

worm or larva reaches maturity. He then bores his way 

out of the fruit, crawls down the tree and buries himself 

about two inches deep in the ground, where he forms an 

earth cell, and in four to six 

weeks emerges as a beetle. The grubs 

rarely mature in apples but the injury 

caused by the egg-laying of the parent 

female heals over, causing. a russet scar, 

and frequently gives the fruit a gnarled 

appearance. Such injury results in a 

large percentage of second grade fruit. 

The beetle winters in some convenient, 

sheltered crack or crevice — sometimes in 

the ground and sometimes in bushes or 

partly decayed fruit. Fruit entertaining 

this pest generally falls from the tree 

before maturity. If it ripens it's a 

"cull," the kind of fruit that is packed 

in the center of the barrel. 

Remedy: During most seasons the 
codling moth spray just after the blos- 
soms fall, with Sterling-worth Arsenate 
of Iiead or Ar-Bo will satisfactorily con- 
trol curculio also, but where severe in- 
jury has been caused previous seasons 
by curculio, and especially if the season 
is rainy, two sprayings are advisable, 
the first being applied just after the 
blossoms have fallen, and the second ten days later. Jarring 
the trees over sheets in the early morning at the time when 
the fruit is setting, and destroying the beetles thus collected 
will materially reduce injury. Shallow cultivation of the 
orchard during the summer will destroy many of the insects 
pupating in the ground and is also an excellent practice for 
preserving the moisture.

GUTWORMS are the young or caterpillars of several 
species of moths. They feed entirely at nig-ht upon 
garden and otlier plants, cutting them off near the 
ground. During the daytime they lie coiled up just 
uuaer the surface of the ground. The eggs are laid in July 
and August, grassland being preferred. Land which has re- 
cently been in sod and planted to crops is likely to be badly 
infested. The eggs hatcli in a short time and the young 
worms feed to some extent in the early fall before seeking 
winter quarters in the ground. Most of the injury is caused 
by these caterpillars in the spring. They become full grown 
the latter part of June or early July, when they crawl into 
the ground and change to pupae, the moths emerging later. 
There is a single brood each year. 

Remedy: Plow or spade up land to be planted another 
season as late in the fall as possible. This will destroy 
many of the worms wintering in the ground. If plants show 
injury, spread poisoned bait such as Sterling'worth Cut Worm.

hatch in five to eight days. The result- 
ing worms are black when first hatched. 
They are heavy eaters and change to a 
yellow color as they grow. They ma- 
ture in two or three weeks and are then 
about one-half to five-eighths of an inch 
long. At maturity they pass down the tree 
and pupate in the ground and emerge 
in about six days as beetles. They en- 
ter sheds, houses or any other sheltered 
winter quarters at frost time and are 
found many times in dwelling houses in 
the spring. Kill them. Don't let them 
out. They want to lay their eggs in the 
trees. 

Bemedy and Preventive: Spray with Sterlingworth Ar- 
senate of I^ead (page 49) as soon as the beetles appear, which 
is about June 17th in latitude of Boston. 

EUBOPEAN COBN BOBEB. This insect is a European 
species which has become established in Essex and Middlesex 
counties in Massachusetts during the past few years. Pres- 
ent indications are that this will be the worst corn pest we 
have. Usually the first indication of injury is the drooping of 
the tassels which are mined out and destroyed by the cater- 
pillars, often before their function of fertilization has been 
performed. This ineans a reduction in the "set" and a loss 
in yield. In addition the caterpillars make feeding tunnels 
all through the stalks and even injure the ears themselves. 
The parent moths are of a deep yellow color and have a wing 
expanse of about an inch and a half. The wings have numer- 
ous zigzag cross lines of a brownish color across them. 
There are two broods of these insects each year, the moths of 
the first brood appearing in May and those of the second 
brood in August. The larvae of this second brood are the 
more injurious and cause severe injury to late corn. The 
larvae of the second brood spend the winter in the stalks, 
change to pvipae in tlie spring and the moths appear soon 
after. 

Control: Since practically all feeding is done within the 
stalks, treatment with insecticides is useless. In the fall 
all corn stalks should be disposed of either by burning, feed- 
ing to livestock, or should be so deeply composted that it 
will be impossible for the larvae to survive. Carelessness in 
overlooking a few stalks, or on the part of a few persons 
in not carrying out these recommendations, may lead to a 
serious infestation again another season.

AFFIiE BORER. Similar to the Round 
Head Apple Borer described below except 
that it attacks the tree trunk higher up 
and many times bores into the small 
branches. Remedy: The same as for 
the Round Head Apple Borer. 

To Prevent: Reduce a quantity of 
Sterling"worth Whale Oil Soap with To- 
bacco (page 47) to the consistency of 
heavy cream by adding washing soda 
and water. To each gallon of this mix- 
ture add two ounces of crude carbolic 
acid. Paint the trunks with this mix- 
ture. 

Remedy: Dig them out with a knife 
when near the surface or kill by running 
a flexible wire into tunnel. If you can- 
not reach borer with a wire squirt a 
little Sterlingrworth Borer Oil (page 50) 
into the tunnel and plug the hole with 
putty. The vapor does the rest. 

FIiEA BEETIiE. This is a small, 
dark-colored beetle that jumps like a 
flea. The hind quarters are more de- v/ORK OF 
veloped than other non-leaping beetles. Tf fa BEETLE C5M 
Th^re are many species and some one ^"-^ 

of these species may attack any vege- 
table or plant. Potatoes seem especially 
attractive. His depredations are char- 
acterized by the shot-like perforations 
made in the leaves. 

Remedy: Sterling-worth Bordeatix 
Mixture (page 45) acts as a repellant 
and has been found most successful in 
preventing injury by this pest. Pota- 
toes should be sprayed with Sterling- 
worth Ar-Bo, (page 48) taking pains to 
cover the underside of the leaves as 
well as above. Sterlingfworth Ar-Bo 
will control the Potato Beetle, Flea 
Beetle and Potato Blight disease. It is 
a combination spray. Spray thoroughly. 

GYPSY MOTH. The eggs are laid 
in the fall by the female moth in clust- 
ers of two hundred to six hundred, held 
together by a sticky hairy covering.

Female Gypsy Moth 



Crevices in bark, grass, stone 
walls, empty cans and bottles, 
birds' nests, wood piles, or any 
other place is deemed suitable by 
the female moth for depositing her 
eggs for the winter. The egg- 
mass is yellowish. No climatic 
change appears to have any effect 
on their fertility. The young 
caterpillar w^ien hatched in the 
spring is about three sixty- 
fourths of an inch long. They 
feed at night and hide during the 
daytime. During his life he 
passes through at least five 
changes. At each change he in- 
creases in size. When nine to 
twelve weeks old he is two inches 
long. At this stage he is hairy, 

dark grayisli in color, and has two rows 

of beautiful colored spots on his back. 

The first ten nearest the head are bright 

blue and the balance are blood-colored. 

It now seeks some sheltered spot, changes 

to the pupae stage and emerges as the 

moth a couple of weeks later. The male 

moths are great day-light fliers. The 

female is larger than the male and meas- 
ures two inches or more from tip to tip 

of wings. She is white in color with 

dark mottled marks across the wings and 

does not fly. 

Control: The Gypsy Moth attacks 

nearly every known tree and plant. The 

most effective way of fighting is to de- 
stroy the egg clusters any time between 

September and April by painting with 

Sterlingrworth Gypsy Motli Creosote, 

(page 51). Banding trees with burlap 

which offers concealment for the moths 

and pupae, helps if you look under the 

burlap daily and destroy all insects gath- 
ered there. It is of no use to burlap 

trees unless you do this. If your trees 

become badly infested through imperfect 

protective measures, spraying with Ar- 
senate of Lead is the only recourse (page 49).

BOBEBS, ETC. — Continued < 

IiEOPABD MOTH. The young or caterpillar of the leop- 
ard moth is a borer in shade trees, ornamentals and other 
plants. Trees in the vicinity of Boston have suffered severely 
from this borer and many trees have been killed by it. The 
parent moth is white, spotted with black and has a wing 
expanse of over two inches. The moths begin to appear the 
latter part of May and are seen until September. The eggs 
are laid in crevices of the bark and the young caterpillars 
from these bore through the bark to the woody tissue be- 
neath. It requires two years for the borers to get their 
growth. They are then about two inches or more in length, 
white in color and marked with numerous tiny black spots. 
^^^hen mature they change to pupae just beneath the outer 
bark, and the moths emerge a few weeks later. It is sup- 
posed that the reason why these borers are so injurious about 
Boston and certain other large cities is the absence of wood- 
peckers and other insectivorous birds in such places. The 
leopard moth has never become a pest in less thickly popu- 
lated places where insectivorous birds are more common. 

Bemedy: Poison sprays are useless against this insect 
since it feeds almost entirely within the wood where it cannot 
be reached by such materials. Infested trees maj^ be detected 
during the summer months, when the borers force large 
quantities of woody material through the openings to their 
tunnels. Badly infested trees should preferably be cut down 
and the w^d burned before the borers can mature. Valuable 
trees or ornamental plants should be gone over carefully and 
a flexible wire or knife used to destroy the borers. When 
these cannot be easily reached, a small quantity of Sterllngf- 
worth Borer Oil (page 50) or Carbon bisulphide should be in- 
jected into the tunnels and the openings closed with putty or 
grafting v.^ax. Both of the above remedies produce a gas 
which penetrates the tunnels and kills the borers. Carbon 
])isulphide is inflammable. Keep all flre away. 

PEACH TBEE BOBEB: This borer is the young of a 
delicate, clear-winged moth, having a blue-black body, an 
orange band across the abdomen and a wing expanse of about 
an inch. The parent moths a'ppear from June to September 
and lay their eggs on the trunk of peach trees near the 
ground. These young bore their way through the bark but 
usually remain close to the surface until the following spring, 
when they bore in deeper, become full grown in early sum- 
mer, change to pupae and the moths emerge soon after. 
There is a single brood each year. The injury by these bor- 
ers causes gum to exude from the tree close to the ground 
and gives the tree a filthy appearance.

GONTTItOIi OP IiXSAF AND PRUIT-EATlMfa, INSECTS 
BORERS, ETC. — Continued 

Remedy: Mound up the earth for a foot or so about the 
peach trees. This will force the moths to lay their eggs 
hig-h^T up where the young- borer can be more readily found 
and destroyed. Do this not later than the first of July The 
trees should be gone over in October, the earth removed and 
the young borers destroyed with a knife, or paint the trunk 
above the mounded earth with Sterling-worth Borer OIL 
(page 50). ^ 

POTATO BUG OR COI.ORADO BEETI.E. This insect 
confines his attention exclusively to the 
potato. He is so familiar we will not 
describe him. The hard-shelled, striped 
beetles lay eggs in yellow clusters on 
the under side of the leaf. They hatch 
in SIX to eight days into a soft, reddish 
slug which does the damage. At ma- 
turity the slugs descend to the ground, 
pupate and form the striped beetle which 
again lays eggs. Two to four broods 
hatch each season. 

Preventive: If you have but a few 
hills, watch for the striped beetles, 
l^ick them and destroy the eggs. Por 
a Remedy, spray with Sterling-worth Ar- 
Bo (page 48). This is a combined poi- 
son and fungous remedy. By using it 
you kill with one spraying the bugs and 
prevent many fungous diseases. Potato 
vines sprayed with this mixture stay 

Potato Bug and Slug green a long time, resulting in a larger 
tuber. It does not cost anything to 

spray with this mixture, for the increase in yield pays for 

time and material. 

ROSE BUG OR ROSE CHAPER. About the first of July 

the female beetle burrows into the 

ground and lays ten to twenty eggs. 
AVorms or larvae hatch in about eight 
days. They are small and feed on any 
nearby vegetation until fall. They hi- 
bernate in the ground during the win- 
ter and dig out in spring, enter the pupa 
state, and emerge as beetles in two or 
three weeks. The beetles which do the 
eating are brown colored, have long 
spindling legs and are great fliers. They 
generally appear suddenly in large num- Rose Chafer

bers and attack roses, ornamental bushes, fruits and vegeta- 
bles, but do their greatest damage to grapes. 

To Protect Grape Clusters: Tie a paper bag about them 
soon after forming. 

Remedy; When possible hand picking and destroying the 
beetles will be found most satisfactory, since they are very 
resistant of poison. Infested plants may be sprayed with a 
strong solution of Sterlingrworth Ar-Bo (page 48) which has 
been sweetened with molasses. Sterling-worth He-Bo (page 54), 
or good, fresh Sterling'worth Hellebore (page 54) has been 
found effective for roses. 

BOUND HEADED AFFILE TBEE BOBEB. This insect 
is hatched from eggs laid by the beetle in the bark crevices 
near the ground. The resulting larvae gradually bores into 
the tree. His presence may be identified by the sawdust-like 
chips which fall from his workshop. At maturity it is nearly 
one inch in length. This insect attacks apple, quince and 
accasionally pear. 

To Frevent: Reduce a quantity of Sterling'worth Whale 
Oil Soap -with Tobacco (See page 47) to the consistency of 
heavy cream by adding washing soda and water. To each 
gallon of this mixture add two ounces of crude carbolic acid. 
Paint the trunks with this mixtrue. 

Bemedy: Dig them out with a knife when near the sur- 
face or kill by running a flexible wire into tunnel. If you 
cannot reach borer with a wire squirt a little Sterlingfworth 
Borer Oil (See page 50) into the tunnel and plug the hole with 
putty. The vapor does the rest. 

SHOT HOI^E BOBEBS. There are several species of tiny 
bark beetles which attack trees in an unhealthy or dying con- 
dition. To Frevent: Cut down and burn the infested trees. 
Bring the others into a healthy state by fertilizing and cul- 
tivation. Paint tree trunks and well up into the branches 
with whitewash to which a little Portland cement and eight 
ounces of white arsenic to each gallon of mixture have been 
added. 

SQUASH VINE BOBEB. This insect is one of the most 
destructive of the many enemies of squashes. The damage 
is due to the larvae boring througli the stems, causing 
them to rot or so injure the vine as to cause the plant 
to wilt and die. These larvae are the young stage of a 
brov/nish, clear-winged moth, having a wing expanse of about 
an inch. The moths appear about the second week in July 
and lay their eggs along the stems. The borers which hatch 
from these eggs feed within the stems and become full grown 
in about a month. They then desert the stems and burrow 
into the earth an inch or two, where they form their cocoons, 
change to pupae and thus pass the winter. There is a single 
brood each year.

A 



CONTBOIk OF IiEAF AND FBUIT EATING INSECTS, 
BOBEBS, ETC. — Continued 

Remedy: The presence of \,he borers feeding within the 
stems often becomes evident by the presence of coarse yellow- 
ish excrement which is forced from the burrows and accumu- 
lates on the ground beneath. The sudden wilting or dying 
of the leaves during mid or late summer is also usually an 
indication of borer injury. When possible, cut out and de- 
stroy the borers and cover the injured portion of the stem 
with earth to encourage secondary roots. These secondary 
roots will carry the plants through and enable them to 
mature their crop. Destroy old plants and dead vines as 
soon as the crop is gathered. Early varieties of squashes 
will act as a protection to late squashes. Plow fields to be 
planted as late in the fall as possible and harrow these again 
in the spring. This will destroy many of the insects winter- 
ing in the ground. Keep the plants vigorous by cultivation 
and the use of fertilizers. If possible do not plant near land 
infested the previous season. 

TENT CATEBFII.I^AB. In the spring about the time 
the foliage begins to expand from the 
buds, small whitish webs are often 
found in the crotches of wild cherry and 
apple trees. These tents are made by 
the apple-tree tent caterpillar, which, 
when full grown is about two inches 
long, black with a light stripe down the 
back and with dots of blue and white 
along the sides, and clothed with yellow- 
ish hairs. As the caterpillars increase 
in size the tent is made larger. The 
tent is the home of the caterpillars on 
cool or stormy days or nights. The 
winter is passed in the egg stage, the 
eggs being laid in a small mass about 
half an inch long and glued to the twigs 
with a sticky substance which hardens 
later. The parent moths are light 
brown in color, have two white bands 
across the fore wings and a wing ex- 
panse of about an inch. These moths 
appear usually during the latter part of 
June. There is a single brood each year. 
Control: ^Vhen possible, destroy 
the winter egg-mass by removing and 
burning. Destroy wild cherry trees 
which are useless and serve as a breed- 
ing place for these insects. While the tents are still small in 
the spring destroy these together with the young caterpillars

in them, by a swab of cloth tied to a

trees with a stiff broom. Do this on a 
cool, dark day or at dusk on a cool eve- 
ning when the caterpillars are all at 
liome. Do not burn the tents off. This 
will injure the trees. The treatment for 
codling moth with Sterlingrworth, Ar-Bo 
(page 48) will destroy the caterpillars 
without further attention if the infesta- 
tion is a mild one. 

TOMATO WORM OR TOBACCO 
WORM. The eggs from which this 
caterpillar is hatched are laid by the 
motli the last of June. They hatch in 
six days, the resulting worm, which 
i-eaclies maturity in about three weeks, 
grows to be three inches long, and in 
diameter to the size of the little finger. 
Projecting from the end of the body is i 
horn a quarter of an incli or more in 
lengtli. These worms burrow into the 
soil at maturity, pupate and emerge in 
the spring as moths. Tomatoes and to- 
bacco are the plants generally attacked. 
Remedy: The worms are so large 
and generally so few that hand picking is 
easy. Spraying with Sterling-wortli Ar- 
senate of Iiead (page 49). five pounds to 
fiftv gallons of water, will be effective. 
' TUSSOCK MOTH. Eggs are laid 
in early fall by the gray-colored wing- 
less female moth. They are shiny 
white in color and are deposited in clus- 
ters of two to three hundred on the 
bark of the tree. They hatch in the 
spring and the young caterpillars com- 
mence eating leaves at once. They ma- 
ture in a month's time, spin a. cocoon 
about themselves and emerge in a short 
time as moths. 

The matured caterpillar is bril- 
liantly colored; head is bright red, body j TU.550CJS. 
gray and covered with long red, yellow (^TEHPIiLAl 

and black hairs and feelers. The under t=r .- _'-.j r-??^^'!L—

CONTROL OF SUCKING INSECTS 

(FZ.ANT Z.ICE OB AFHIDS, SCAI.E INSECTS, ETC.) 

'UCKING insects have a beak M-ith which they pierce 
beneath the surface of the host and extract the juices 
from within. Where sucking insects are feeding, the 
tissues a!e not actually eaten but the extraction of 
the juices causes a withering, curling or dying of the affected 
portion, and an examination will usually disclose the pres- 
ence of insects of this type. A CONTACT INSECTICIDE is 
necessary to control such insects and since each insect must 
be hit by the spray in order to be killed, thoroughness of 
application is very essential. First determine what sort of 
an insect you are dealing with, tliat is. whether it is a chew- 
ing insect or a sucking insect, and then apply the proper 
remedy at the right time. 

APHIS OR PLANT LICE. There are hundreds of species 
of this insect. They attack both root and leaf of nearly all 
plants, shrubs, trees and vegetables, and get their sustenance 
by sucking the sap. Fifteen or twenty species do most of 
tlie damage in this climate. They are all minute. Some have 
wings and some are wingless. Those attacking the roots of 
plants and trees are as a rule blackish or bluish in color, 
while those infesting leaves and stems of plants and vege- 
tables are generally greenish in color. There are exceptions 
but generally speaking the above color description holds. 
The color appearance is often changed by a covering of dust. 

Those species which infest leaves will generally be found 
on the under side and in the process of feeding they roll or 
curl the leaves. One of the recent additions to this family 
is the Green Pea I^ouse. His body is about three-sixteenths 
of an inch long, spread of wings the same. His color is the 
same as the pea leaf which he makes his host. 

The process of development of plant lice or Aphis is re- 
markable. The female lays her eggs in the fall, from which 
a colony of females hatch in the spring. These females give 
birth to live young without intervention of the male, which 
multiply so rapidly that the progeny of one female left un- 
disturbed would reach several million in a season. 

Preventive: Examine the roots of all shrubs or trees 
before setting. If you have a suspicion of lice oj' eggs in 
dirt clinging to the roots, mix the soil that is to be next to 
the roots with fine powdered tobacco (page 53) and moisten 
with water so as to make a "mush" before setting tree into it. 
Ants are fond of Aphis because these tiny insects furnish 
them with a sweet substance called honey dew, and in return 
protect and spread them from plant to plant in caring foi- 
them. To keep the ants down, band your trees and shrubs

Aphis on Apple leal 



with some sticlcy substance like tanglefoot. Put a collar of 
sticky fly paper one inch wide around your dahlias and sim- 
ilar plants. This will stop the ants. 

Remedy: Poisons are not useful 
aerainst them. Sterlingfwortli Kerosene 
Emulsion (page 4 9), Sterlingworth Whale 
Oil Soap with Tobacco (page 47), Ster- 
ling-worth Scale Killer (page 50), Ster- 
ling-worth Plant Lice Killer (page 56), 
are all reliable sprays for those species 
which attacl<; vegetables, shrubs and trees 
above ground, but we particularly rec- 
ommend the last named for house plants. 
For those lice which attack the roots use 
Sterlingworth Mag-g-ott Acid (page 51), 
and Sterlin^worth Fowdered Tobacco 
(page 53). 

Always spray the under side of the 
leaves. If leaves are rolled or curled 
dip them in the spray. Your spray or 
dusting powder must come in contact 
with the body to kill. For those lice which make the roots of 
the tree their host, like woolly aphis, soak the ground around 
plant with Sterlingworth Kerosene Emulsion (page 49) or 
Sterling-worth Mag-g-ot Acid (page 51). 

InEAF HOPPERS. These insects are about one-eighth 
of an inch long, have blunt heads and 
are striped with yellow and red. They 
are quick long jumpers. They work on 
the under side of the leaves and by 
sucking the sap cause them to dry up 
and die. They hibernate in rubbish 
heaps, grass or any sheltered place dur- 
ing the winter; emerge in early spring 
and lay eggs just beneath the surface 
in clusters of eight to ten. From these 
the young white hoppers hatch in about 
two weeks. 

They attack all kinds of plants, but 
principally the grape, and are hard to 
combat. An ounce of prevention saves 
weeks of spraying, so watch the under 
side of leaves and if the small, white 
young appear, spray quickly with 
Sterling-worth Kerosene Emulsion (page

ONION THBIPS. This insect is almost microscopic in 
size, and causes by its sucking- injury to the onion known as 
silver top. white blight, etc. Entire fields of onions are often 
ruined by this species which also attacks various other gar- 
den plants. 

Control: As soon as injury becomes evident, spray the 
plants with any one of the following remedies: — Sterling-- 
worth Whale Oil Soap with Tohacco (page 47), Sterlingworth 
Kerosene Emixlsion (page 49), or Sterling-worth Plant Lice 
Killer (page 56). Spray thoroughly, covering the plants as 
well as the ground just around them. It might be found de- 
sirable to repeat the operation in about a week's time. 

OYSTEW SHELL SCALE. These insects remain in the 
ef^g state under the female scale until 
about the first of June. They then appear 
as minute white crawlers. They settle 
and commence to penetrate the outer bark 
and suck the tree juices. 

The adult scale can easily be deter- 
mined bj^ the shape of its back, which re- 
sembles an oyster shell. Poplars, Wil- 
low, Lilac, White Ash, and Apple are the 
plants most often infested seriously. To 
destroy — spray with Kerosene Emulsion 
(page 49) or a solution of Sterlingworth 
Whale Oil Soap with Tobacco (page 47) as 
soon as you see the young crawlers. If 
you spray regularly for San Jose Scale 
that spraying will take care of the Oyster 
Scale also. 

RED BUGS OP THE APPLE. These 
insects have became quite prevalent in 
Oyster Shell Scale Massachusetts the past few years and 
on twig their injury to the fruit and foliage of the 

apple is now not an infrequent occurrence. 
The injury to the fruit is characterized by a stunting or 
puckering of the surface, accompanied by pits or depressions, 
due to the punctures made by the insects in feeding. The 
injury to the leaves is comparatively unimportant. The life 
cycle of the two common species of red bugs is very similar. 
The eggs hatch soon after the opening of the leaves of the 
fruit buds and the minute red nymphs at once begin to feed 
upon the tender leaves, usually causing clusters of small red 
dots by their punctures. As soon as the fruit sets, it is at-

tacked and frequently injured to such an extent that it drops 
prematurely. 

Remedy: If injury by these insects is suspected or has 
occurred during previous years, spray the apple trees thor- 
oughly just before the blossoms open 
with Sterlingrworth Whale Oil Soap with 
Tobacco (page 47) or with Sterlingworth 
Kerosene Emulsion (page 49). A second 
application may usually be made to ad- 
vantage just after the blossoms 'fall, 
combining either of these materials with 
your codling motli spray. Red bugs are 
very wary and even in badly infested 
orchards are so agile in hiding that it is 
difficult to locate them. 

"BED SFIDEB." This is not a true 
insect but belongs to the spider group, 
being almost invisible to the naked eye. 
It has long been one of the most serious 
pests with which growers of greenhouse 
cucumbers and other plants have had to 
contend. It is estimated that green- 
house men in Eastein Massachusetts 
lose a total of no less than $100,000 each 
year due to the destructiveness of this 
pest. Various fruit, ornamental plants, 
shade trees, etc., growing out of doors 
are also subject to injury, which con- 
sists of the extraction of the juices from 
the foliage, causing the leaves or stems gradually to dry up 
and die. All feeding is confined to the under side of leaves. 

Control: Recent experiments conducted at the Massa- 
chusetts Agricultural Experiment Station have demonstrated 
conclusively that "Red Spider" can be controlled and injury 
to greenhouse cucumbers and other plants prevented by a 
thorough application of Linseed Oil Emulsion. Sterling'worth 
Bed Spider Emulsion (page 53) is prepared according to the 
approved formula and with our facilities for manufacture, it 
will be found cheaper and more efficient than the home made 
emulsion. On plants growing out of doors which are less 
susceptible to spray injury, Sterling'worth Kerosene Emulsion 
(page 49) or Sterling'worth "Whale Oil Soap with Tohacco 
(page 47) or Sterling'worth Plant Lice Killer (page 56) will be 
found effective. Spray the under side of the leaves and spray 
tlioroughly. Begin spraying as soon as injury is evident. 
Don't delay.

l)est of the twentieth century. Recent investigations by Dr. 
Marlatt, of Washington, seem to prove quite conclusively 
that the original liome of the San Jose Scale is in Cliina. 

The full-grown scale is about, the size of a pin-head 

round in sliape and grayish- 
brown in color. It attacks 
bark, leaves and fruit. The 
part seen is not the Insect but 
the shell or scale which cov- 
ers it. 

If tlie scale be lifted by 
Ivnifu or pinpoint, an orange- 
yellow specie may be seen, 
which is the insect. Each 
female produces in June or 
July, three hundred to five 
liundred young, whicli are 
born alive. Tlie young rest 
on the barl<; and feed on the 
sap through the beak. They 
mature and produce young in 
about a month. It is esti- 
mated that a single female 
produces upwards of three bil- 
lion insects in a single year. 
The light-colored scales 
about the diameter of a com- 
mon pin which have just set- 
tled down, as well as somewhat 
larger and darker scales about 
the size of a small pin-head, 
may i^erhaps also be observed against the smooth bark on 
young wood. When the bark becomes quite thoroughly cov- 
ered with the scales it assumes a rather rough, scurfy ap- 
pearance of an ashy-gray color. When rubbed with the hand, 
or better, with the thumb-nail, a yellowish liquid appears, due 
to the crushing of hundreds of insects. This liquid gives a 
greasy feeling to tlie bark wliere it has been rubbed. On very 
young wood, especially if of a bright greenish color, the scale 
will be surrounded by a reddish discoloration. This is true 
mIso on fruit, and of course it shows best on green fruit and 
on light-colored varieties. Care must be used, however, not 
to confuse the red spots formed by fungous diseases, such as 
Entomosporium maculatum, with those of the scale.

coloration, be stripped off so as to disclose the inner green- 
colored portion, this will also be found discolored in the same 
way as described above, if the scale is present. 

Remedy: Agricultural Experiment Stations recommend 
Lime and Sulphur Wash Sprays and Miscible Oil Sprays, as the 

most satisfactory. 
These should be ap- 
plied in the fall or 
winter when the 
tree is dormant, or 
in the early spring, 
and in case of badly 
infested trees in 
both fall and spring. 
For a quick, effec- 
tive remedy when 
you can spray but 
once and must give 
the tree prompt re- 
lief we recommend 
Sterlingfworth Scale 
Killer (page 50). 
Where you can 
spray regularly use 
Sterling'worth Ijime 
and Sulphur Wasli 
(page 46). 

If you discover 
your trees are in- 
fested after the 
leaves have sprung, 
paint the trunks 
and large limbs with Sterling-worth Whale Oil Soap with To- 
bacco (page 47) and spray the leaves with a light application 
of either Sterling'worth Scale Killer (page 50) or Sterling'- 
worth Kerosene Emulsion (page 49). This will hold the scale 
in check until you can treat when tree is dormant with 
Sterling'worth Scale Killer or Sterling-worth Iiime and Sulphxir 
"Wash. This pest attacks all fruit trees, many shrubs and 
vines and some shade trees. 

SPRUCE GAImIm IiOUSE. Injury by this pest results in 
the formation of somewhat cone-like, many-celled galls of 
about three-quarters of an inch in length, usually accom- 
panied when the infestation is bad, by a more or less severe 
dropping of foliage. Norway and white spruce are attacked

most. There are two broods of these gall lice each vear hut 
only one of these makes galls. The e|gs of thi first genera- 
tion are laid about the middle of May iS'clusters on ?he^spru?e 
bark These eggs hatch in about a 
week and the young crawl about and 
hnally settle down at fresh galls just 
started by the parent gall lice. As the 
galls develop they gradually close over 
these insects, leaving them in small 
chambers surrounded by the outer par- 
tition of the gall. Early in August the 
insects become full grown and about 
this time the galls, which have previ- 
ou.sly been green, turn yellow, dry and 
split open, permitting the full grown 
lice to escape. The latter part of Aug- 
ust the eggs of the second brood are 
laid. These hatch late in the fall and 
the young pass the winter in protected 
crevices of the bark, continuing their 
development the next spring. 

Control: Success in the control of 
this insect means 
spraying with the 
l)roper material, at 
the proper time 
and spraying tlior- 

oughly. Sterling-worth Wliale Oil Soap 
with Tobacco (page 47) or Sterlingworth 
Kerosene Emulsion (page 49) will control 

this insect. The proper time to spray 

is during the month of April, the earlier 

the better. Don't delay. After the galls 

start to form, spi-aying is useless. Cut- 
ting off and burning the galls in June 

will help control this species but this is 

hardly practicable except in the case of a 

fevv' small plants. 

SQUASH BUG. The mature squash 

bug is of a gray-black color and slightlv 

over a half inch long. The younger bugs 

are of a gray color and usually feed in 

groups on the under side of the leaves. 

The eggs are brown and are laid in 

clusters on the under side of the leaves. 

Injury consists in the extraction of the juices of both leaves

and stems by all stages of the insect from the 
young- to the adults. Serious infestation often results in the 
death of the plants in a short time. 

Remedy: Place pieces of boards, shingles, etc. among 
the plants. The adults will seek shelter under these at night, 
where they may be found after dark or in the early morning, 
and destroyed. Destroy the eggs whenever these are found. 
The best way is to cut out the small section of the leaf 
bearing them and burn it. These remedies are, of course, 
liracticable only over small areas. Spray the young bugs 
with Sterling-worth Whale Oil Soap with Tobacco (page 47) or 
Sterling-worth Kerosene Emulsion (page 49). Each bug must 
be hit by the spray. While the plants are still young, keep 
them well cultivated and use a fertilizer to make them grow 
vigorously. Dust the plants thoroughly while young with 
air-slaked lime. This will repel the bugs and they will search 
for plants elsewhere upon which to lay their eggs. As soon 
as the crop is gathered, rake up the plants, allow them to 
stand for a day so that the bugs can collect on them again, 
and then destroy bugs by spraying with kerosene oil. 



CONTROL OF 
SUBTERRANEAN INSECTS 



^^^^.^HESE insects work in the soil and are perhaps the most 
£ C\ difficult of all to control, since they are not easily 
»^ ) reached and direct methods of control are not always 
^^^ practicable. Subterranean insects feed both by biting 
off, chewing and swallowing solid food, and by piercing and 
sucking, according to the species. 

GRAPE ROOT WORM. The mother beetle appears at 
blossom time, feeds a little and lays from one hundred to five 
liundred eggs on the bark. They hatch in two weeks. The 
young larvae, which are about one-sixteenth of an inch long, 
drop to the ground and commence to grope around in search 
of food. Upon locating the vine trunk they work themselves 
down to the roots and feed. The larvae hibernate deep in the 
ground. In the spring they come near the surface, form an 
earthy cell and change into a beetle. 

Remedy: Sprav with Sterling-worth Arsenate of Lead 
(page 49). Immediately when the beetles appear — before

CONTBOZi OP SUBTERRANEAN INSECTS — Continued 

they lay eggs — agitate the ground by cultivation when larvae 
are near top of ground. 

LETTUCE EABTH-IiOUSE. A cream-colored louse with 
short legs, extracts the sap from the roots of the lettuce be- 
low ground. For a remedy use Sterling-worth Magrg-ot Acid 
(Pcige 51) around stems. 

BOOT MAGGOTS. There is a large number of these 
jtests but they all have the same contemptible destructive 

disposition. These maggots 
"railroad" your radishes and 
turnips, and make the roots of 
your cabbages and cauliflower 
look mostly like holes. This is 
one of the meanest garden pests. 
You never see him or his work 
until the damage is done. Pre- 
ventive measures are best. Al- 
ways sprinkle a ring of Sterling"- 
worth Powdered Tobacco (page 
53) around your Squash, Cu- 
cumbers, Melons, Carrots, Rad- 
ishes and Turnips as soon as 
they are up. When transplant- 
ing cabbages do the same, or 
better still place a Sterling-- 
worth Tarred Pelt Disks (page 
51) about each plant. This helps 
keep off the fly that lays the egg. 
Make a practice of digging around 
the roots of those vines favored 
by this insect every few days and 
if you have suspicion that he is at work apply Sterling^worth 
Mag-grot Acid (page 51) at once. If you find your vines wilt- 
ing don't lay it to drought or something else, look for root 
maggots and if you find them, treat all your vines with 
Maggot Acid or be prepared to lose your crop. 

WHITE GRUBS. These are without doubt the most de- 
structive pests with which the strawberry grower has to con- 
tend and various other crops, such as corn, potatoes, grains, 
grasses, etc., are frequently injured. These large, thick 
bodied, curved, whitish grubs are the young of the May 
Beetle or "June Bug," and require two years for their growth 
and change to the adult beetle. 

Treatment: The parent beetles prefer to lay their eggs 
in sod land or in land poorly cultivated and weedy. Crops 
such as strawberries, corn, potatoes, etc., should not follow

i 



within two years land that has been in sod, since, owing to 
the lack of food, the grubs concentrate upon the roots and 
soon kill them. Clover, beans, peas, etc., are not injured to 
any great extent by white grubs and may be grown to advan- 
tage as a two year intervening crop between sod and straw- 
berries, corn, potatoes, etc. Nothing 
can be done to prevent injury to plants 
after it has been started. 

WIRE WORMS. These are the 
young of a "click" or "snapping beetle." 
They are usually yellowish-brown in 
color, about three-fourths of an inch to 
an inch long, slender and quite hard, 
and are especially injurious to corn and 
potatoes. 

Remedy: T^ittle can be suggested 
in the way of a remedy for these pests. 
The mid-summer cultivation of fields 
already planted will destroy many of 
the insects in their pupa cases at this 
tim.e. and the plowing in mid-summer 
of fields in sod which are to be planted 
another season will greatly reduce in- 
jury by these pests. Various insecti- 
cides which have been experimented 
with up to the present time have proved useless from a prac- 
tical standpoint.

MISCELLANEOUS INSECT 
PESTS 

OUB CREATOR after making Man, seemed to feel that 
he was likely to be a "lazy cuss," and to keep him in 
motion and in a healthy, active state, turned seven 
million insect pests loose in his cave with the injunc- 
tion to sting, suck, eat. drink and be merry, and ever since 
then Man has been swatting flies, chasing fleas, killing lice 
and hunting bed bugs. 

Man has certainly had to "sit up and take notice," do a 
little scratching and then keep on taking notice and doing a 
lot more scratching to keep ahead of these enemies. Between 
his nightly battles with the mosquito who pumps disease

MISCZ:x.I.ANEOUS INSECT PESTS— Continued 

into him and the bed bug: who sucks blood out of him and a 
multitude of other insects who keep him on the move to pro- 
tect his property daytimes the original plan for "motion" and 
"activity" has worked out perfectly. 

THE MOSQUITO. This is a real "honest to goodness" 
dangerous pest. Never allow one to bite you If you can help 
it. Kill him as quick as he lights. Don't wait to see how he 
works "his auger." Kill him. Just think of a mosquito 
satisfying part of his appetite on a big fat black water snake 
and finishing out on you. Never visit or live in a place where 
there are mosquitoes, if you can avoid it. You cannot tell a 
malarial mosquito from any other, except by close examina- 
tion and disease is about sure to result if one of them punc- 
tures your skin. You would not intentionally let a mad dog 
or rattlesnake bite you. Take the same precaution ag-ainst 
mosquitoes. Cover all stagnant water with oil. Permit none 
to stand on your premises or on your neighbors' if you can 
help it. Mosquitoes always breed in stagnant water. This 
applies to water in eave troughs, cisterns, barrels, sink drains, 
cess pools, ditches, swamps, etc. Keep your houses screened 
and protect the toads and insect-eating birds. 

THE PLY. The fly is more dan- 
gerous than the mosquito, a lot more 
filthy and is with us a longer period of 
the year. He breeds in filthy places, 
and then walks over your food and 
wipes his feet on your skin. He can 
carry more disease and plant it more 
quickly than any other insect created. 
Typhoid fever, tuberculosis, cholera, 
dysentery, small pox, leprosy, are a few 
of the diseases he dispenses. Swat him. 
Catch, him in traps, destroy his breed- 
ing places. Don't buy milk from 
any one who does not take precautions 
to keep flies out of the barn at milking 
time. Screen your homes, cover the 
garbage can, destroy the fly maggots 
breeding in the out-of-door water clos- 
ets by a treatment every two weeks 
during the late spring, summer and early fall, with borax 
water at the rate of three-fourths of a pound of borax to ten 
gallons of water. In manure piles and hog pens, where about 
95 per cent, of house flies breed, spray the manure and straw 
at least every two weeks during the fly season with good 
fresh Sterling-worth Hellebore (page 54) solution, at the rate 
of one-half a pound of the Hellebore to ten gallons of water, 
extracting the Hellebore in solution for 24 hours before ap-

plication. Borax solution is also very effective, but Is dan- 
gerous to plant life where the manure is to be used as a fer- 
tilizer. See that the g-round around the pile for a yard or two 
is given a g-ood drenching- also. Many of the maggots come 
out here to change to pupae. Spray horses and cattle with 
Guaranteed Cattle Oil (page 55). 

ROACHES AND WATER BUGS. These insects live in 

tlie most filthy places imaginable. Sink drains, cess pools 

and garbage cans are favorite "resi- 
dential .'sections." They are nocturnal 

in their habits and do their crawling 

at night. After thoroughly inspecting 

the sink spout and garbage can, they 

start out loaded with filth in search of 

food. Your food is theirs, so they head 

for your pantry. They creep over your 

pastry, crawl tlirough your packages of 

cereal and burrow in the contents of 

your flour barrel, leaving a trail of sink 

filth and disease behind them. They 

have just one redeeming feature — they 

eat bed bugs. You seldom find a large 

number of bed bugs where there are 

many roaches. Perhaps that sickness 

that laid you up last year or came near 

being fatal to "the little one" was 

caused by one of these pests. It is no 

disgrace to have roaches, for they may 

be brought in from many different 
sources over which you have no control. 
The disgrace is in keeping them. It is 
not hard or expensive to exterminate 
them and Sterlingrworth Boacli Killer 
(page 69) will do the work. As a pre- 
ventive keep all food tightly covered — 
keep the sink clean and cut off every 
source of food supply. They will leave 
your premises if you don't furnish 
them food. 

BED BUGS. These are so familiar 
in song and story that they do not need 
any description. If you can't see them 
you can generally detect their odor. 
They may be brought in on your clothes, 
in the laundry, the grocery baskets or 
on the dog. It is no disgrace to have them. The disgrace is 




The Roach

MISCEI.Z.ANi:OUS INSECT PESTS— Continued 



in keeping them. Their habits of concealment, infrequency 
of feeding, nature of their food which consists of human 
blood and members of their own tribe, make them hard to 
combat. The Sterlinafworth Bed Bugf Preparation (page 68) 
and persistence will be found as effective if it can be used. 
Closing infested rooms tightly, burning sulphur candles (page 
52) and thus subjecting the rooms to a fumigation for a peri- 
od of at least 48 hours will aid materiallv. 

THE BUFFAIiO BUG. This is another bug that has re- 
cently crawled into the limelight. 
He came from Europe, and made 
himself at home at once. He is 
harmless with the exception that his 
specialty is eating carpets, at which 
trade he works industriously. He is 
a broad, oval-shaped beetle, almost 
a quarter of an inch long, with a 
red stripe down the middle of his 
back. Eternal vigilance is the best 
remedy. If you use rugs on the 
floor occasional cleaning is a protec- 
tion, but in the case of carpets 
whicli are not often taken up, close 
watching is necessary. It is claimed 
by some that strong, fine powdered 
tobacco sprinkled around the floor 
before the carpet is tacked is a 
preventive. 

THE ANT. They are the classiest 
"bug"' in the insect kingdom. They rank 
in almost the same order of intelligence 
as Man. They are wonderfully active, 
and the stunts they do would make suit- 
able material for a moving picture show. 
Tlie only sure way to keep them off your 
premises is to dig a canal around your 
property and fill the canal with water. 
There are about fifteen thousand species, 
of which five thousand have been classi- 
fied, but the housewife knows just two 
— "the big black fellow" that tunnelled 
the custard pie the day that the minister 
came to tea, and the little red fellow who 
pulled the cork out of the molasses jug 
and crawled in. When not chiseling 
into the sugar bucket they are out in the 
lawn cutting off grass roots and making 
ant hills. You seldom see many ants

where there are plenty of toads. Put a toad down where ants 
are plenty and watch the fun. If you keep food covered and 
crumbs brushed, it helps to keep ants out of the house

THE FI.EA. When David Harum said, "A reasonable 

amount of fleas is good for a dog 
— they keep him from broodin' on 
being a dog," he didn't know 
what he was talking about. 
Either David never had fleas or 
they didn't like the taste of his 
skin and did not bite him. At 
any rate, one good healthy en- 
ergetic flea in full possession of 
ri ^ 'nfc ^^^ faculties can keep a family 

T>r./-t rJ^ + 1^0 Wi^ °^ fifteen, including the cat, dogf 

jjog or cat Ilea '^ and goat, guessing and scratch- 

ing and miserable. They never 
play fair, they jump so quick you can't get a good square 
lick at them. We haven't a thing to suggest for them on hu- 
man beings. For dogs and cats Sterlinsrworth Flea Killer 
(page 69) is satisfactory. 

BATS AND MICE. The "rat problem" Is one of the most 
serious that ever confronted man. A single pair will increase, 
if left unmolested, to twenty millions in three years. His 
bill of fare includes almost everything eaten by man and a 
number of articles not included in the human dietaries; for 
instance, mice, living horses' hoofs, kid gloves, shoes and 
paper. It is estimated that a single rat will eat 60 cents' 
worth of g-rain in a year if fed on that alone. 

The damage they do is not measured wholly by what they 
eat. Through pollution of food products, they do as much 
damage as by eating. Their energetic habits of digging under 
buildings, through embankments, g-nawing wood, cutting holes 
in sacks, tearing up papers to make nests, add to their list of 
depredations. The killing of young chickens and fowls, and 
the stealing of eggs have brought them into disrepute among 
poultrymen. 

They distribute disease and their well known fondness 
for matches has resulted in many disastrous conflagrations. 
They must be exterminated wherever found. There are in- 
numerable receipts for driving them; singeing their hair off, 
tieing a bell around their necks, or painting them red and 
white and turning them loose among their friends, are all 
supposed to be sure drivers, but we have always noticed that 
the fellow who had the most "dead-sure" receipts had the

most rats. We believe that cats, traps and Rat Killers offer 
the surest solution. For a poison that generally acts with- 
out unpleasant results, one not likely to injure human beings 
or pets, try Sterling-wortli Rat Killer (page 67). 

There are a score of other pests that at times make the 
housekeeper wish she was not. Among them are cheese 
mites, clothes moth, ham beetle, yellow-jackets, fish moth, 
meal worm, punkies, but they are rather infrequent and do 
not often carry contagion, or do much damage. 

FOUXiTBY IiOUSE. There are a number of species of 
this particular enemy of the poultry- 
men. Some poultrymen who have 
fought them claim there are at 
least a million different and distinct 
species. What lice do to offset the 
efforts of the Women's Anti Egg Trust 
Clubs to keep down the high cost of 
eggs is a shame. They are the per- 
sonification of persistency boiled down. 
They feed upon scales of the skin, 
hairs, feathers, etc., and cause the 
poultry to become sickly because of 
their irritation. Success with poultry 
and lice never occupy the same poul- 
try house at the same time. If your 
fowls are lousy either kill the lice, kill 
the fowls or quit the poultry business. 
Preventives and Remedy: Pow- 
ders are most effective against this 
pest, for the lice remain on the fowl's 
body and are not easily reached by 
fluids There is a different Lice Pow- 
der for every ten square miles in the 
United States. No doubt an occasional 
infirm louse about ready to "pass out" 
is helped "on his way" by some of the 
stronger powders, but it is a waste to 
spend money on a large proportion of the Lice Powders offered 
for sale. Don't buy a powder that does not kill the lice so 
you can brush them out of the fowl's feathers or so you can 
see them fall dead from the fowl. Don't think because it is 
called Lice Powder it will kill lice. Let your eye prove its 
efficiency (page 63). 

CHICKEN MITES. These mites are just as fatal to suc- 
cess with poultry as poultry lice. They are nocturnal in their 
habits. They seclude themselves in the cracks and crevices 
of the poultry house daytimes and at night attack the fowls 
while they are roosting. They subsist upon blood and no fowl

can meet the demands made upon her for 
blood by this thirsty blood sucker, retain 
her health, and do her duty as an egg: pro- 
ducer. No poultryman can afford to feed 
mites with blood generated from feed at 
the present high prices. 

Remedy: Get after them in the 
cracks and crevices where they live day- 
times with a good strong liquid lice and 
mite killer. The stronger the better. 
Use a fluid that has evaporating qualities 
and throws off a vapor. The vapor from 
such killers penetrate where the fluid 
would not, and helps kill. Do not at- 
tempt to fight them with watery mix- Chicken Mite 
tures, kerosene, etc. They are worthy of 

your most energetic and constant attention (page 62). A 
little crude carbolic acid mixed with the whitewash used when 
spraying your hen house helps as a preventive. 



FUNGOUS DISEASES 

ELJNGOUS diseases are unlike insects that you can see 
and crush between two bricks. They are caused by 
microscopic, parasitic plants which live within the 
tissues of higher plants and obtain their sustenance 
from them. These parasites produce a diseased condition on 
the plant that harbors them. Plants that entertain fungous 
parasites are called host plants. There are few vegetables, 
plants or trees that are not host plants for at least one 
species of fungi. 

The injury from fungi is as serious as from the eating 
pests but the cause is invisible and only the result can be 
seen. The materials mostly used in fighting it are Lime, 
Sulphur, Copper. Ammonia or Iron. Treating plants that have 
been attacked helps some, but far better results are obtained 
by anticipating the trouble and getting in preventive work 
first. Generally speaking fungous preparations should be 
considered as preventives rather than remedies. Crops like 
potatoes should not be planted unless you plan to spray them. 
No good first quality fruit should be expected unless you spray* 
for the various fungous diseases to which they are subject. 
Spraying for fungi costs nothing as the additional increase in 
crop and better fruit and vegetables more than pays the bill. 
The following are some of those prevailing fungous dis- 
eases at this time affecting the most important crops.

PUNGOUS DISEASES— Continued 



ANTHRACNOSE. Attacks nearly all fruit and vegeta- 
bles in some form. It appears most fre- 
quently on the bean, attacking both pod 
and leaf. Cucumbers and melons are also 
favorite host plants. Its presence is indi- 
cated by unsightly spots on the leaf. Pre- 
ventive: Plant seed free from disease. 
Remedy: Spray plants when three inches 
high Avith Bordeaux Mixture (page 45) and 
repeat in two weeks and again after plant 
blossoms. Do not cultivate, walk through 
the rows or pick beans while wet with dew 
or rain. The disease is easily spread in 
this way. 

APPZiE SCAB. This disease shows 
itself early. A cold, rainy season is most 
favorable for this scab fungous. It can 
easily be determined by the almost black, 
dark-green, circular fuzzy spots on the 
fruit. The infected fruit many times 
drops before maturity, sometimes cracks 
open and is often badly out of shape.

tion and with one spraying get after 
both the codling moth and apple scab. 
Sterling-worth Ziinie and Sulphur Wasli 
(page 46) may be used as a substitute 
for Bordeaux. 

BZiACK KNOT. This disease at- 
tacks the plum mostly. Swellings 
on the limbs and twigs appear like 
bunches of hard, rough black warts. 

Remedy and Preventive: We 
know of no sure remedy or preventive

helpful. Look the tree over when 
leafless and cut off all knots and burn 
them.

FUNOOT7S SZSSASES — Continued 

BiCISTER BUST: This is a clisea,se of the white pine and 
other pines v/ith needles in groups of five. The disease is 
native to Europe but was introduced into the United States 
several years ago on infested 
pine nursery stock. It has 
now become established in this 
country and offers a serious 
menace to the growth of white 
pine. The fungus parasite re- 
quires two host plants to com- 
plete its life cycle, the pines 
mentioned being one host and 
currants or gooseberries the 
other. The disease developes 
in the wood of the pine from 
spores from infested currant 
or gooseberry plants, upon 
which only the leaves are at- 
tacked. The disease once 
started in a pine gradually 
kills the parts attacked and 
eventually the tree itself. The 
fungus fruits in the spring, 
usually in April or May, upon 
the pine and breaks out as 
small orange colored patches 
surrounded by a white papery 
envelope. These orange spores 
are blown about by the wind 
and in turn infect any currant 
or gooseberry plants which 
happen to be within several 
hundred feet, causing a brown- 
ish rust upon the under side of the leaves. Thus the cycle 
continues. One pine cannot infect another. The disease must 
spread to currants or g'ooseberries and then liack to pines. If 
you know of or suspect the existence of this disease either on 
your own premises or the premises of others, communicate 

Fig. 1. — Diagram indicating the life circuit of the causal 
fungus of the white-pine blister rust, a. Blisters on pine in 
May and early June, from which the disease spreads to cur- 
rant or gooseberry leaves and produces the early summer 
stage, b; thence it may spread to another currant leaf and 
produce there a second crop of the early summer stage, c, or 
it may produce the late summer stage, d; in this stage, in the 
fall, it infects neighboring white pines, which may or may not 
include the pine (a) which bore the blisters that started the 
outbreak the preceeding spring. Bulletin 742 '(U. S. D. A.)

'at once with your State Agricultural Experiment Station, ac- 
companying- your information with specimens if possible 
Every one must do his part to stamp out this disease 

Remedy and Preventive: Once the disease is established 
in a neig-hborhood, the only salvation of the pines lies in the 
destruction of all currant and gooseberry plants within five 
hundred feet of the infected pines, to prevent the infection 
from spreading. Infected twigs, branches, and the trees 
themselves, m severe cases, should be cut and burned 

BBOWN SPOT. This disease seems to attack the Bald- 
win exclusively and m.ake the fruit look as if specked with 
small rotten circular spots. 

To Prevent:* Spray with Sterling-worth Bordeaux the 

same as for Apple Scab. 

CANXEB. This disease attacks nearly all fruit trees, 
and should be given prompt attention as soon 
CANKER/j^ as it appears. 

OSJ iM Remedy: When it appears scrape off all 

APPLE mi loosened bark near the seat of the trouble. Cut 
TWIG ^l out and burn small branches affected. Cover 
wounds with melted asphaltum after first disin- 
fecting with corrosion sublimate solution 1 part 
to 1000 parts water and dig out the canker 
sores. We know of no reliable preventive 
measure. 

CHESTNUT BI^IGHT. This disease, also 
of foreign origin, has for a number of years 
been killing thousands of chestnut trees in 
Eastern United States. The infection is spread 
from tree to tree by the agency of the wind, birds, insects. It 
will probably be years before this disease runs its course, and 
it is hoped that in time a variety of chestnut resistant to the 
disease will be developed and thus prevent this valuable tree 
from being exterminated. 

Control: Nothing can be suggested other than to cut 
and utilize chestnut timber as soon as a tree shows evidences 
of the disease. 

DOWNY MIZ.DEW AND BBOWN ROT. When this dis- 
ease attacks fruit it is called Brown Rot, and when it attacks 
leaves — Dov/ny Mildew. As Downy Mildew it attacks melons, 
cucumibers, squashes and grapes. You can detect it by the 
mouldy yellow spots on the underside of the leaves. These 
spots after a short time turn brown. The leaf wilts, dies and 
drops to the ground. When the disease appears get busy. A 
few hours' delay may mean the difference between a crop and 
no crop.

Spray witla Ster-ling-worth Iiiquid Bor- 
deaux (page 45) to hold it in check and 

confine it to plants already infested. 

GBAFE BIiACX BOT. The first 

warning is in the form of brown spots 

on the leaves and soon after the grapes 

turn dark and shrivel up. 

Remedy: l-se Sterling-worth Iiiquid 

Bordeaux (page' 45), or Sterlinffworth 

Dry Bordeaux Pungficide (page 46). 

IiEAF SPOT. This disease shows 

itself in form of small circular brown 

spots on the leaves. It attacks most all 

stone and pome fruits. We know of no 

certain safe remedy. S t e r 11 n g" worth 

liicLuid Bordeaux (page 45) is sviggested 
as a preventive. 

OAT SMUT. This disease attacks 

all grains and is sometimes called Bunt 

or Black Head. The last name describes 

its appearance. Soak seed in Sterlingf- 

worth No Scab (page 61) 

PEACH I.EAF CUBZi. Crinkley, 

puckered leaves, taking a powdery ap- 
pearance later on, is indicative of this disease. The leaves 

turn yellow and fall to the graund. As a preventive we rec- 
ommend Sterlingworth Iiiine and 
Sulphur Spray (page 46) early in the 
spring before the opening of buds. 
Some growers prefer Bordeaux sprays. 
PEACH YEi:.I.OW. Fruit from 
trees infested generally ripens early 
and has reddish-yellow streaks run- 
ning from skin to the pit. Peculiar 
yellowish sickly shoots sprout from 
the old wood. This is an extremely 
contagious disease for which no cure 
is known. Burn the tree where it 
stands and scatter lime liberally on 
the ground covered by the tree to 
kill spores and disinfect the soil. 
Be particular to burn trees where 
they stand. You may distribute the 
disease if you move them. Remem- 
ber this is as contagious among trees 
as small-pox is among human beings.

Preventive: Spray with Sterl- 
inffworth Iiiquid Bordeaux (page 45) 
every two or three weeks from about 
July 10th to August 15th. Jf you 
spray with Sterling-worth Ar-Bo 
(page 48) this spraying- takes care 
of bugs and blight at the same time. 

POTATO BOT AND Z.ATE 
Bl^IGHT. This disease shows itself 
as a whitish mold on the under side 
of the leaves. When j^ou see this 
look out for rotting potatoes. Use 
the same preventive for this as for 
Early Blight. 

Spraying potatoes for fungus 
costs nothing, as the increased crop 
pays liberally for time and materi- 
als. Spraying is part of "the game" 
the same as hoeing-. Buy your ma- 
terials when planting so as to have 

them on hand. This applies to both the gardener with fifty 
hills and to the large raiser with fifty acres.

STCRLINa CHEMICAL CO., CAMBRIDSE, MASS. 



This causes roug-h, scabby potatoes. 
It is usually prevented by soaking the 
seed in Sterling-worth No Scab (page 
61). Never plant potatoes on soil that 
has raised scabby potatoes. Never use 
seed unless you sort it. The addi- 
tional crop more than pays for the 
trouble and expense. 

SOOTY SPOT. Looks something 
like Scab but Is not so fuzzy, more like 
an ink spot or paint stain and makes 
the fruit dirty. We do not know of a 
certain remedy but believe a spraying 
with Bordeaux when the fruit is about 
one-fourth grown helps. Attacks 
apple mostly. 

SHOT-HOI.E FUNGUS. This is a 
very destructive disease to the plum. 
This same fungus attacks the cherry. 
It sometimes completely defoliates the 
tree and practically ruins the fruit. 

Remedy: Spray with Sterling-- 
worth Iiiquid Bordeaux when leaves 
are half grown and again in two 
weeks.

BORDEAUX MIXTURE 

WHAT IT IS A?TD ITS USE 



4 



© 



OBDEAUX MIXTURE is a fungicide, made by com- 
bining- the Milk of Lime witli Copper Sulpliate. It 
derives its name from having been first used in or 
near the city of Bordeaux, France, and is considered 
by many the most reliable and effective remedy for most 
fungous diseases infesting vegetation. 

The value of Bordeaux Mixture cannot be over-estimated. 
T!ut it musl be properly prepared from suitable materials. 
Some recommend the use of equal parts of Lime and Copper 
Sulphate in malting, but we believe that most authorities rec- 
ommend the use of a quantity of Lime slightly in excess of 
the Copper Sulphate, especially if it is to be used in com- 
bination with a poison. 

Its use prevents or controls certain Scab, Leaf Spot and 
Sooty Mold of the apple, Anthracnose of the' Bean, Black- 
berry. Raspberry and Grape, Leaf Spot of the Beet and checks 
the ravages of the Flea Beetle, many of the Rusts, Leaf 
f'>]ights of Currant and Gooseberry, Celery, and Pear Blight. 
Downy Mildew of , the Cucumber, Melon and Squash. Potato 
Blight, Black Knot. Shot-hole fungus; also many Fungous 
Diseases, Blights and Leaf Spots that attack Shade Trees. 

Primarily it is a fungicide, but when combined with a 
l)oison, as Paris Green, Arsenate of Lead, London Purple, cal- 
eium arsenate, etc. (see Sterling-wortli Ar-Bo page 48), a val- 
uable mixture is obtained which in addition to the fungicidal 
properties kills and controls Bud Moth, Canker Worms, Codlin 
Moth (which make your apples wormy) Curculio motli, Aspar- 
agus Beetles. Cabbage Worms, Slugs, Currant Worms, insect 
attacking Cranberries, Striped Cucumber Beetle, which at- 
tacks your Squash, as well as Cucumber vines, Squash Bugs. 
Flea Beetle on Grape and Potato vines. Rose Bug, Potato 
Beetle (potato bug), etc. It may be used as a liquid or Dry 
Powder. We believe the liquid form is the best for most 
purposes. 

It is a compound of remarkable adhesive properties. 
When it becomes dry on tlie foliage, it resists excessive 
washings of rain for some time. 

Bordeaux is a remedy and it is for use as a preventive 
rather than a corrective. One thorough spraying at the right 
time is worth more than ten careless treatments. Almost 
any of the spray pumps will do the work satisfactorily. The 
spray should be sent against the vegetation in a fine mist 
with some force. If a spray pump is not available, it may be 
applied with brush and pail. Early applications on the apple

CERTAIN 
FUNGOUS 
DISEASES 






It may be combined with a poison when de- 
sired (full directions are on the can), so 
combined it becomes a combined Fungicide 
and Insecticide, and kills many eating insects 
as well as remedies most fungous diseases, 
but for a combined insect killer and fungous 
remedy we recommend Sterling-worth Ar-Bo (See page 48). 

The selection of materials used in the manufacture of 
Sterling-worth Iiig.uid Bordeaux is made with great care, and 
the resulting combination has given satisfaction for over 10 
years. Careful selection of materials and great care in its 
preparation are essential to greatest success. The kitchen 
gardener and small groAver will find it more satisfactory to 
buy his Bordeaux ready to use than make it himself and 
many large users find that it is cheaper to buy the ready- 
made material when he figures the cost of the labor and the 
utensils spoiled in making it. 

Sterlingrworth Ziicitiid Bordeaux is about the consistency of 
putty or paste. One gallon makes from 10 to 50 gallons (de- 
. pending for what purpose it is to be used) of mixture ready 
to use by adding water. Explicit directions for use on every 
can tell hov/ to use it on each kind of vegetation. If you 
only have one grape vine or one fruit tree or a 100-square-foot 
garden you can afford to spray. Yovi cannot get the best 
fruit or vegetables unless you lise a fungous preventive.

BORDEAUX MIXTURE What It Is and Its Use 

" (Continued from Page 44) 

of Bordeau.x Compounds do under certain climatic conditions 
cause rusting. Avoid using Bordeaux or Compounds of Bor- 
deaux except in settled weather. Sudden change in tempera- 
ture and damp rainy weather are believed to be favorable to 
Bordeaux injury. We believe that the injury likely to be done 
by Bordeaux to be less than that done by the disease against 
which it is used. Bordeaux should not be used on Japanese 
plum or similar tender leaved foliage. Its use on Melons and 
Cucumbers is sometimes followed by injury, but as such 
crops are generally completely ruined by disease, unless pro- 
tected, the beneficial results more than offset the injury done.

This is a fungicide in pov/der form for accomplishing the 
same results as Iiiquid Bordeaux (page 45). It is not for kill- 
ing insects. For a dry powder Bordeaux Insect Killer, see

It is used either as a dust or it may be mixed with water 
and used as a spray. 

As a dust for fruit trees (except Japanese plum and other 
trees with tender foliage), etc., it is used by adding fifteen to 
twenty pounds of lime dust to one pound of Bordeaux; for 
potatoes, two to five pounds of lime to one pound of Bordeaux 
gives best results.

KIIiIiS TWO 

BIRDS WITH 

ONE STONE 

A COMBINED INSECTICIDE 
AND FUNGICIDE 

You kill two birds with one stone and 
gret the stone back when yoix use Sterlingr- 
worth Ar-Bo, for you prevent certain fungroiis 
diseases and kill most leaf-eating- insects at 
one spraying-, and the quality of the increase 
yield pays for the cost of the material and time of applying. 

Sterling-worth Ar-Bo has the fungicide qualities of Bor- 
deaux and the killing- values of Paris Green and Arsenate of 
T^ead combined in one mixture. It is useful wherever straight 
Bordeaux Mixture is useful in the way of preventing fungous 
diseases like Anthracnose, Leaf Spot, Black Rot of the Grape 
and Apple Downy Mildew, Leaf Curl, Sooty Blotch, Fruit 
Spot of Apple, Leaf Blight of Pear, Black Knot. Potato Blight, 
Phytophthoi-a Rot. and in addition it controls most eating 
insects like Bud Moth, Canker Worms, Codling Moth (which 
makes your apples wormy), Plum Curculio (which stings 
your apples, plums, cherries, etc). Asparagus Beetle, Cabbage 
Worm, many Slugs, Currant Worms, certain insects that at- 
tack cranberries, the Striped Cucumber Beetle which attacks 
your squash as well as cucuml^r vines, grape and potato 
vines. Rose Bug and Potato Bug. 

For Plum, Cherry and other stone fruits, which have 
tender foliage, the same care must be taken in its use as in 
the use of Bordeaux. It is not for use on Japanese Plum or 
Peach. 

Sterlingfworth Ar-Bo is the great potato spray. By its 
tonic properties on potatoes it helps produce a larger yield of 
superior quality and it gives the crop in many instances three 
or more weeks longer in which to mature. Every day's addi- 
tional growth means larger tubers. Perfect fruit cannot be 
expected unless you spray with proper materials. Nearly all 
fruit and vegetables should be sprayed. The additional yield 
more than pays for the spraying materials and the time re-

A IiZNSESD OIL EMUIiSION 

The GreeahoTise "Red Spider" has long^ 
betn one of the most serious pests with 
which growers of greenhouse plants have 
had to contend. Cucumber plants are often 
seriously injured, and various ornamental 
plants are no less immune. 

Control. Recent experiments conducted 
at the Massachusetts Experiment Station 
have demonstrated conclusively that "Red 
Spider" can be controlled and injury prevented by a thorough 
application of I^inseed Oil Emiulsion. Sterling'worth Red Spi- 
der Emulsion is prepared according to the approved formula 
and will be found a cheaper and more efficient remedy than 
the home made emulsion. 

Directions. Apply as a spray to the under side of the 
leaves, so that an even film is formed. Spray thoroughly. 
Repeat in seven days' time to kill individuals that were in 
the egg stage at the first application. PRICES: 1 quart 50c.;

FBOTi:CTS STOCK FROM FIiIES 






All we ask 



Buy a can of Cruaranteed Cattle Oil. Use 
it as directed and if it does not protect your 
cattle and horses from fiies and mosquitoes 
to your satisfaction, you to be the judg^e of 
what constitutes satisfaction, return the 
empty can to the dealer from whom you made 
the purchase and he will return to you the 
purchase price. We leave the matter of what 
constitutes satisfaction entirely to your honor, 
is that you use it as directed, grive it a g'ood, honest, fair trial. 

Guaranteed Cattle Oil is as good an article as we can make 
regardless of price consideration. Thousands of cans have 
been sold under the above "Money Back" guarantee and during 
the five years it has been on the market less than 10 cans 
have been returned. We claim that when properly used it 
will protect cattle all day in ordinary weather. It does not 
taint the milk and is not disagreeable to use. 

It is to some extent useful against lice on cattle and horses 
but we do not recommend it for lice, as any preparation strong 
enough to be a good lice killer will blister the animal if it is 
used for a fly spray. Guaranteed Cattle Oil may be used 
with a brush or sprayer. The Delug'e Sprayer described on 
page 60 is one of the best for applying. 

Guaranteed Cattle Oil does not depend for its effectiveness 
on killing flies but on the fumes and odor which arise from 
it. Flies hit by the fluid are killed, the others are kept off by 
the odor. 

Read what we say about flies on page 19. , These filthy in- 
sects spread disease and by continually annoying stock cause 
it to lose flesh and injure its health. Use Guaranteed Cattle 
Oil and your cows will be insured perfect rest; will feed in 
peace and quiet and will give you a maximum quantity of milk 
on a minimum quantity of food. It pays a big profit to pro- 
tect milk cows from flies. 

Order Guaranteed Cattle Oil from your dealer. If he does 
not have it and will not furnish it, or offers something else, 
send us his name and address and we will send you a gallon 
can for one dollar, charges paid. This offer is only good to 
points east of the Mississippi.

Dip a stick into a can of Sterlingworth Anti Crow Com 
Oil and stir it around in a peck of corn until the corn is dark-

through a seeder, or you can mix a gallon of Sterling-worth 
Anti Crow Com Oil with two gallons of hot water and add the 
corn while stirring. The oil will give it a thin crow-protect- 
ing coat, which is an easier and cheaper way of protecting 
your newly planted corn from crows and blackbirds than by 
"scarecrows." Do not confuse crow oil with so-called "Crow 
Tar" or corn tar. It is different in odor, and stronger. One

cheapest, quickest and best method of killing weeds. 

Ground treated with Sterlingworth Weed Killer may be

quick and sure for killing poison ivy in walls or places where

plied with an ordinary watering pot. One pound makes ten

We have manufactured Sterlingf- 
worth. Lawn Compound 6 years. It gives 
universal satisfaction. We guarantee tliat 
it will kill weeds such as plantain, dan- 
delions, chick-weed and most other weeds 
having a broad hairy surface without 
killing the grass. Money back if it fails. 

Sterlingrworth Lawn Compound is a non-poisonous dry 
powder for sowing on the lawn and adheres to the broad flat 
leaves of such weeds as those named above. It does not stick 
to the grass because of its upright position and smooth sur- 
face. The ingredients in combination with the sun's rays 
burn out the weeds. The compound has an invigorating 
effect on the grass, wliicli stimulated by it springs up rapidly 
and gets ahead of the weeds tliat have been stunted and 
killed by the compound and quickly cliokes them out. The 
use of Sterlingrworth Lawn Compound helps give to the grass 
a beautiful rich bottle-green velvety color so much admired 
by lovers of good lawns. Two applications will clean out 
the most heavily weeded lawn. In many instances one ap- 
plication will do it. Do not dig out weeds, it leaves bare 
spots and holes. Sterling-worth Lawn Compound is easily 
applied by sprinkling over the weedy lawn. One pound will 
dress 100 to 200 square feet, depending on the lawns con- 
dition. ' 

Sterlingfworth Lawn Compound is only for destroying 
weeds where there is grass. Most Seedsmen and hardware

If, after using* Sterlingrworth Iiiquid l^ice 
and Mite Killer, you do not believe it is better 
than any other preparation you ever used 
for killing" lice and mites in poultry houses, 
state the facts to us and we will refund the 
purchase price without quibble or question. 

It requires an entirely different method to rid poultry 
houses of mites than to kill lice on fowls. No powder is en- 
tirely satisfactory for this purpose, for these blood-sucking 
pests inhabit cracks and crevices in the building where it is 
impossible to reach with a fluid or powder, and it is neces- 
sary to depend upon a gaseous vapor to penetrate their hiding 
places. Read about lice and mites on page 35. 

Sterling'worth Iiiquid Xiice and Mite Killer has a double 
value. It kills bj" contact, and the vapor thrown off by its 
wonderful evaporating qualities helps kill certain vermin. 
Poultrymen who do not find mites on their fowls should not 
be led to the delusion that their houses are free from them, 
for they^ attack fowls when they are on the roost at night, 
suck their blood during the sleeping hours and hide in their 
retreats under the roosts or in crevices during the day. 

To treat a large number of fowls, apply liberally to nests, 
roosts, supports and dropping boards. 

For young" chickens. Paint the bottom of a box with the 
liquid and cover with a thin layer of straw. Place the young 
chickens on the straw and cover the box with bagging. 

To kill lice on hog's. Spray bedding and rubbing posts 
thoroughly. 

PRICES: 1 qt. cans 35c., mailing" weig"ht 4 lbs.; 2 qt. cans 
60c., mailing weight 7 lbs.; 1 gallon cans $1.00, mailing" weig'ht 
11 lbs.; 5 gallon jacket cans $3.50. 

STERLINGWORTH MOUTH SPRAYER 

It is used by placing the long end in the fluid to be sprayed 
blowing through the short flat end. With it the under side of 
the leaves may be sprayed where plant lice, aphis, spiders 
and other crawlers which infest house plants usually work. 
Just the thing for applying Sterlingworth Plant Iiice Killer 
(described on page 56), or any other fluid. PRICE: 10 cents; 
pp, 15 cents.

satisfactory, you to he the sole judffe of what 
constitutes satisfaction, return to us the box con-

believe that this is the best roup "cure macie" and make this 
extraordinary offer to convince you of its absolute reliability. 

Roup is one of the most common, most contag-lous and 
most fatal diseases v/hich afflict poultry. It frequently 
starts with a simple cold and if unchecked quickly spreads 
through the entire flock. The symptoms are odorous dis- 
charges at the mouth and nostrils followed by swelling of the 
head and quick breathing. The fowl has an offensive breath 
and canker spots sometimes appear. For years this terrible 
disease raged unchecked and killed millions of fowls. It can 
now be prevented and relieved with this remedy which is ad- 
ministered in the sick fowl's drink and in this way they take 
it. If the disease is so far advanced that the fowls cannot 
see to drink, tlieir heads may be bathed in the medicine until 
they have sufficiently recovered to drink. Use a little of this 
remedy in the fowls' drink as a preventive of roup, canker 
and common colds, and you will save much trouble. It is 
an excellent remedy for canker. Ask your dealer to get 
Sterling"worth Roup Renxedy^ "the-money-hack-the-no-cure-no- 
pay-kind." If he will not supply you or offers something 
else, write to us for special prices to agents and make inoney

The fellow who claims that egg tonics are useless and 
should not be fed to hens is the fellow you meet most fre- 
quently in the drug store buying- spring- tonics, cascara, quin- 
ine or liver pills. Careful inquiry will generally show that 
he believes in "dosing" himself, wife, horse, dog, cow and 
cat. but on the point of "heping- out" the hen he takes a dif- 
ferent stand. You will generally find that he bases his judg- 
ment upon the use of the old style filler eg'g foods which con- 
tained so much useless filler that a hen had to eat a bushel 
or so of filler to get one dose of medicine. By "filler" we 
mean bran, screenings, and other low-priced materials used 
to make the package look "a lot for your money." 

Sterling"worth Hgg Tablets contain no "filler" and if a 
tonic is good for man and domestic animals, why not the hen. 
These tablets are as larg-e as a five-cent piece and over 
an eighth of an inch thick and contain more egg-stimulating 
tonic value than is contained in a pint of many filler egg 
foods. They are used by dissolving in water or may be 
crushed into powder and given either in the fowl's drink or by 
moistening food with the water in which the tablets are dis- 
solved or mixed dry with mash foods. The best way is to 
feed in the food. Full directions on every package. Agents 
wanted in every town. Send for agents' prices on dozen lots.

dry up or internally embalm the carcass makes it useable In

A FOWEBFUZ^ ODOBZ.Z:SS FI.ANT 
INVIGOBATOR 

Nothing adds more to the appearance of 
the home than a window garden of healthy, 
blooming plants. Nothing cheers the sick 
more than flowers, and few things give so 
much pleasure to the housewife as her potted plants. 

Sterling-worth Plant Tablets were originated and first 
used by a chemist who loved flowers and made their care and 
attentior a "hobby." His plant-loving friends had such won- 
derful success with the tablets he gave them that he was 
induced to offer them for sale, and from this love of the 
beautiful and spirit of kindness, the present world-wide 
business in Sterling-worth Plant Tablets has grown. 

They contain those ingredients in their proper propor- 
tions that are necessary for healthy plant life. Their use 
promotes a luxuriant, vigorous growth of branch, leaf, and 
flower. Users have told us that they "double the bloom." 

Renewing of plant soil is made less important and is 
less frequently needed, when these tablets are used. They 
build up the soil, and supply scientifically the elements neces- 
sary to a wholesome growth. 

Sterlingrworth Plant Tablets are more effective than what 
is commonly known as "liquid manure," which contains much 
waste matter which pollutes the soil and is generally accom- 
panied by a disagreeable odor. 

Thousands of plant lovers who do not keep plants would 
do so they knew how beautiful and luxuriantly they could 
make them bloom by feeding with Sterlingrworth Plant Tab- 
lets. To those who have plants that are not as beautiful as 
they should be we say, "try these tablets just once, the cost 
is trifling, the results wonderfully satisfactory." When you 
learn how satisfactory they are, you will buy more. They 
are used by dissolving in water and watering the soil with 
the solution. Tell your plant-loving friends about them. 
They are sold by thousands of florists, druggists, seedsmen 
and agents throughout the United States and Canada. Agents 
who can devote a little time to selling these tablets will find 
the profits satisfactory. Write for prices on dozen lots, 

PRICES: ^arg-e size (250 tablets sufficient for 35 plants 
for eig-ht months) 50 cents, postpaid; medium size (100 tablets 
sufficient for 35 plants for three months) 25 cents postpaid;
